Takana lets you see your SCSS and CSS style changes live, in the browser, as you type them.
Install the takana command to your system path:
$ npm install -g takana
Run takana by specifying the root of your project directory:
$ takana /path/to/project_folder
Now add the JavaScript snippit to any page you want to live update:
<script type="text/javascript" src="http://localhost:48626/takana.js"></script>
<script type="text/javascript">
takanaClient.run();
</script>
Finally open the web page that you pasted the snippit into on the previous step. Then open one of its referenced stylesheets in Sublime and start live-editing!
“{{t.body}}” — {{t.name}}
